Welcome to WebmasterWorld Guest from 18.104.22.168
I did a little digging and came up with this host name: x1crawler.x-echo.com. Is that the one you hit with password protection? It's ip = 22.214.171.124 and x-echo.com's IP is 126.96.36.199. Looks like
they have a beefy server, they are running Apache/1.3.3 (Unix) mod_perl/1.21 and PHP/3.0.12.
According to a RIPE lookup the class C is in France
inetnum: 188.8.131.52 - 184.108.40.206
descr: Socite ECHO
status: ASSIGNED PA
changed: email@example.com 19970514
And the whois [networksolutions.com] is also goes back to France. Strange huh?
For some unknown reason I've been unable to the get to the bottom of, my ISP has LOST the site logs for the offending dates! Grrrrr.
Without being able to check, it is difficult to confirm. I'm still working on this to find out what happened to the logs.
